US West Coast: on frontline from nuclear cloud?

“California is closely watching the crisis at a Japanese nuclear plant, but officials downplayed the threat that a radioactive cloud blown across the Pacific could pose for the US West Coast.

While radioactivity could reach the United States from the quake-hit Fukushima plant, the levels would not be high enough to cause major health problems, said the Nuclear Regulatory Commission (NRC).

Some experts disagreed, notably pointing to the west-east jet stream, but NRC — which was asked by Japan on Monday to send nuclear experts to deal with the crisis — said even the Pacific island state of Hawaii faced little risk.

‘Right now it’s quite possible that there could be some radiation floating over the United States. But we don’t think that it would be particularly harmful… even in a worst case scenario,’ spokesman David McIntyre told AFP.”
